parece estar tomada en la ruta actual a Chile aun sin pavimentoThis photography has to the back dates February, 1950 seems to be taken in the current route to Chile even without pavement

is really(exactly) from Chile, from a place that is called a " Jump of the Soldier ", to about 20 km from the city of The Andes. There the river Aconcagua has perforated a cut of almost 200 mts of depth and about 10 of width. The FFCC crosses it to average atura entering a curved tunnel (left side) and going out of the bridge across another curved tunnel (right) after this one another tunnel comes semi curved from about 20 meters and then a bridge of aprox 50 mts to return to take the left side of the river. Undoubtedly it is an impressive place and still it is in service since it is used by the train that takes copper from Saladillo towards The Andes.
